Solution:
A circle is a collection of all the points in a plane which are at a fixed distance from a fixed point in the plane. The fixed point is called the center of the circle. The fixed distance is called the radius of the circle. Non-collinear points are those points that do not lie on the same line.Since the circle has to pass through all the three non-collinear points, only one circle can be drawn.
Therefore, option 1 is correct.
